Ruling in Sony vs. Datel Case by German Federal Court of Justice: Consequences for Gaming, Cheat Tools, and EU Software Copyright Legislation

The German Federal Court of Justice (BGH) has made a groundbreaking decision on July 31, 2025, clarifying the legal status of cheat software in video games. Guided by the Court of Justice of the European Union's (CJEU) interpretation, the BGH has established that cheat software which alters RAM data does not infringe copyright.

This ruling pertains to cheat software that manipulates game variables in RAM without modifying the actual program code. Such software, according to the BGH, does not constitute a copyright infringement under EU law. However, it's important to note that other types of cheat software that alter or reproduce protected code or content could still be considered violations of copyright law.

The implications of this judgment extend beyond the realm of cheat software. It may also be relevant for modding tools, debugging software, or interoperability solutions in the software industry at large.

For video gaming publishers, this ruling underscores the need to adopt a multi-faceted approach to disincentivize the use of cheat software. Copyright law alone is insufficient, and publishers must implement technical protection measures, enforce End User Licence Agreements (EULAs), and consider alternative legal approaches.

The message for publishers is clear: they must prevent cheating through technical means, not solely relying on copyright law. This judgment reinforces a narrow interpretation of software copyright, which could foster innovation in the accessory market.

However, the judgment also provides legal certainty for cheat software developers. They must ensure their code remains unmodified and that no technical protection measures are circumvented to remain on the right side of the law.
